(Alteration)

Components:  V, S, M
Duration:  1 round per 3 levels upon use
Casting Time:  1 round
Area of Effect:  Edged weapon touched
Saving Throw:  None

When cast on an edged weapon, the weapon will become a weapon of sharpness upon its next use, and will remain that way for 1 round per 3 levels of the wizard. The weapon may not be magical, except if subject enchant an item.
The spell adds no plusses to the weapon (it severs on a 20), but plusses due to quality or enchant an item do apply. The material component is a mithril razor enchanted to +3 with enchant an item, costing 500 gp. The spell can be made permanent, but to do so requires a specially forged weapon, and a miniature version of the weapon forged from the same metals in lieu of the razor. The total cost is at least 30,000 gp.
